Looks like my drive is more consistent than SynbiosVyse's but we do know that he played with compression.
One thing that distinguishes "my" drive from the other SF drives is that it has RAISE, not sure what to make out of that difference, yet.

I'm not sure that the Mushkin doesn't have RAISE. I know most 60's weren't supposed to have it, but given the available capacity of 55GB and the total NAND of 64GB, I think it has it.

Incidentally, I believe the Chronos Deluxe 60 has been discontinued. Here in the US, you can buy a 120GB toggle NAND model for $180 to $220, but the 60GB toggle NAND model is $140. That's not a great deal, and I think once retailer stock ends you won't see them anymore.

The Mushkin has been running for exactly 10 days straight as of a minute ago, 240hours
That's not bad, as uninterrupted I pull down 10.5 to 10.8TB a day.

When Intel talk about relocated sectors are they talking about pages or a block? One_Hertz has 7,257 relocations and 25nm NAND. If a page = a sector that equates to 56.7MiB. If a block = a sector that would equate to 14.2GiB.

34nm = 4kiB page & a 0.5MiB block, so a retired block count of 5 = 2.5MiB. If the Chronos has 9GiB spare area and RAISE is deactivated it looks like it will have some way to go yet.

JESD218 states (for endurance) that the SSD must:

The SSD maintains its advertised user capacity.
The SSD maintains the required UBER for its application class
The SSD meets the required functional failure requirement (FFR) for its application class.
The SSD retains data with power off for the required time for its application class. (1 year for client, 3 months for enterprise)

i sincerely appreciate your new charts, but wondering if there is a normalized value chart? that would help my brain to wrap around the data a bit better...
very hurt at the loss of Vapor on the project, i hope that everything is fine, his health and that of his family as well.
Is there any type of communication or is he incommunicado? If we could at least get a PM shot his way maybe he could send the graph files that he made so that they can be updated by others...i mean damn his charts are the best i think ive seen.

Vapor=HELP! We miss you!

The drive has somewhere between 6.5-8GiB spare area. But spare area indicator was calibrated to go to 1 for 2.74GiB which is the difference between GiB and GB. If a sector is a page, then it makes no sense to decrease MWI to 1 so fast. But if one reallocation is a block, then it makes sense for 512KiB blocks, which scales perfectly, as there were ~5600 reallocations when MWI hit 1. Could it be that drive has actually 34nm NAND? or this was already physically checked?

^ Intel 25nm NAND is spec’d at 5K P/E cycles. It makes sense that a relocation would be a block rather than a page, but if that is the case the capacity of the drive must have been reduced.

I have emailed Vapor. Let’s see if he replies. I hope all is well. If we have not heard from him by next week I think someone else should take over the charts until such time as Vapor returns. I could host the excel charts on my Live Sky Drive account, which means anyone can get access to them. If anyone testing has excel charts that they would like to post send me a pm and I will give you my email address.

I fired up my rig again last night after several days of it staying off to check data retention. All is well. I have yet to get to the samsung because I don't seem to have a 5-6 hour block of time free to play with it

^ Seems that reallocation rate is decreasing... Could you post the values of all SMART parameters, I am interested more in Erase Fail Count. If reallocation sector count is counting page reallocation, then erase fail must count block reallocation.

I'm glad you tested the power-off data retention on the Intel. Do you remember how many days it was powered off?

I got a Windows detected a hard disk problem pop up message, but everything appears to be fine. It triggered for the Mushkin, but for no apparent reason. All SMART stuff seems to be unchanged from last night, still 5 retirements.

Second: The M4 is dead. Just like the Samsung 470 it couldn't last without power for some time, in this case 9 days. I've tried to power on and off, and i several pc but no luck. Do you have any ideas I should try?

Third: The MTRON is something wrong with. I've tried it in my foldingrig but without any luck. I get the same problems as before and the system feels sluggish and sometime hangs. I'm going to send it back to GullLars and he can rma it. They come with 5 years warranty som he might get something new and shiny

The Intel X25-M G1 and the Kingston V+100 is back in the test again and all looks normal at this moment.

Wow! That's out of the blue! I was hoping it would make it to 1PB. Looks like Vertex Turbo is the one which has the 1PB torch in hand now.

May be we should take a break on Vertex Turbo and have it sit idle, powered off for few days to see if it still keeps going! I have a vague memory that bluestang has been powering it off during the day on working days.

It seems that the MWI might not be so overly conservative after all. 1 year to hold data without a charge after the MWI has expired seems excessive. I wonder how much the MWI would change if the requirement to hold data changed to 3 months as it is with enterprise.
